- Patented peeilfligiiii London, England, have invented 'certa new and useful Improvements in Processes Treating Petroleum or other Hydrocarbon; Oils, of which the following is-a specifipa; tion.

This invention'relates to improvements in process of treating petroleum or other hydrocarbon oils such as kerosene, petroleumdistillates, especially light hydrocarbon oils;

.;tiallodorless oil together of a specific gravity approximating from lighting oils, benzin, shale The object of the invention is to produce a highly rectified or refined and substanwith a valuable resi ue. i .The process according to this invention for treating oils of the kinds described consists adding to the oil an alkaline extract of seaweed and-also asaponaceous substance with or without sulfuric acid.

' According to one modification of the proc ess the seaweed is added to an alkaline lye and the saponaceous substance is, afterward Y incorporated with the solution thus formed.

[According to afurther modification the saponaceous substance maybe. repared by treating a saponaceous of alkaline lye.

plant w t a solution? In apreferred: process the alkaline solu-- tion containing the seaweed extract ismixed I with asaponaceous substance and the mix? ture is added to the oil to be treated. Sulfuric acid is then added causing a brisk efiervescence. The oil can then be separated by decantation or by any other convenlent method. The residue remaining after the removal of the oil is of value for both com mercial and scientific purposes.

One inethod of carrying this invention into effect: is as follows :-A mucilage s prepared from seaweed in the followmgimanner.- solution of'carbonate of soda in water at 90-100 F. is made in the proportion ofvlfl'b. of carbonate of soda toll alv i lon of water. Quicklime is then adde in and-the mixture is stirred-and allowed'ito l the proportion of about -1- lb; to thej'gallon settle The supernatant liquid will be solutionof gcaustic soda, enough lime vhaying been added t05'carry down allthe carbon ie 'lihe proportions given apo ve', are

To this fluid-various ;-chem1cal reagents may be addedrfiora the 5 purpose of precipitating certain impurities hoi n the mineral oil), for example-common salt'in the proportion of 1} l-bf. r: gallon or iron oxid the proportion o lb; I per g lbh may bhdded or both, these.

It is a feature of the resulting oil that itis freed from sulfur and does not generate carbon monoxid gas when burned or when used in an internal combustion engine.

It is possible to employ almost any class of seaweed 'but'it'is' preferred to use-that known as Algae which has a' form resembling maidenharr, fern. It is not essential .-that the-seaweed should be broken upand ground although it advantageous to the process to do so. I The sapon'aceous plants employed maybe selected from any of the 0llowing:-quillai bark, Acacia 'co'ncimta bean, Entada scan (Jens bean, a big nut called by the natives of India and Mexico the ritta nut.

It is within this invention to add the saponaceousu plant directly to the seaweed ex tract instead of extracting it in the manner I described.

to secure by Letters-Patentis 1. A process forthe treatment of-oilsof thckinds described which consists in adding to the oil an alkaline mucilage prepared .from seaweed and a vegetable saponaceous from? seaweed and a vegetable saponaceous allniline detergentzand sulfuric acid.
